I've been using my Nikon 85mm 1.8 for a while now and it wasn't as sharp as I expected. After reviewing some images I noticed it was back-focusing a lot. I did an af fine-tune and on a scale of -20 to +20 it was at between -10 and-16. This was a new lens out of the box.
Fortunately I noticed a) that is wasn't as sharp as I expected b) that it was back-focusing and c) that this was a fairly easy fix. I imagine a lot of people end up using a lens that's permanently out of focus.
My question is whether this is due to inconsistencies in the lens mount on the lens, the camera flange, or some software issue. If it's the lens, surely they can check them after they've been made?? And if not, surely there should be some instructions on how to do it that come with the lens. Like when you get a new TV you have to programme the channels or whatever.
I guess once it's been bought, if the buyer knows enough about photography to notice there's an issue they'll know how to fix it? If not, then though luck...
